Ignite your taste buds with this famous flame-cooked dessert that was invented in 1951. What's in our Banana Foster? Bananas, vanilla ice cream and a special sauce. The rich sauce (made of butter, brown sugar, spicy cinnamon, dark rum and banana liqueur) is expertly flambéd with the bananas in a hot saucepan, before being served atop the ice cream. Hot meets cold in this perfect pairing of tastes.
